++;bindaddr=0.0.0.0
++;port=4520
++;
++; Our entity identifier (Should generally be the MAC address of the
++; machine it's running on. Defaults to the first eth address, but you
++; can override it here, as long as you set it to the MAC of *something*
++; you own!)
++;
++;entityid=00:07:E9:3B:76:60
++;
++; Define the max depth in which to search the DUNDi system (also max # of
++; seconds to wait for a reply)
++;
++ttl=32
++;
++; If we don't get ACK to our DPREQUEST within 2000ms, and autokill is set
++; to yes, then we cancel the whole thing (that's enough time for one
++; retransmission only). This is used to keep things from stalling for a long
++; time for a host that is not available, but would be ill advised for bad
++; connections. In addition to 'yes' or 'no' you can also specify a number
++; of milliseconds. See 'qualify' for individual peers to turn on for just
++; a specific peer.
++;
++autokill=yes
++;
++; pbx_dundi creates a rotating key called "secret", under the family
++; 'secretpath'. The default family is dundi (resulting in
++; the key being held at dundi/secret).
++;
++;secretpath=dundi
++;
++; The 'storehistory' option (also changeable at runtime with
++; 'dundi store history' and 'dundi no store history') will
++; cause the DUNDi engine to keep track of the last several
++; queries and the amount of time each query took to execute
++; for the purpose of tracking slow nodes. This option is
++; off by default due to performance impacts.
++;
++;storehistory=yes
++
++[mappings]
++;
++; The "mappings" section maps DUNDi contexts
++; to contexts on the local asterisk system. Remember
++; that numbers that are made available under the e164
++; DUNDi context are regulated by the DUNDi General Peering
++; Agreement (GPA) if you are a member of the DUNDi E.164
++; Peering System.
++;
++; dundi_context => local_context,weight,tech,dest[,options]]
++;
++; dundi_context is the name of the context being requested
++; within the DUNDi request
++;
++; local_context is the name of the context on the local system
++; in which numbers can be looked up for which responses shall be given.
++;
++; tech is the technology to use (IAX, SIP, H323)
++;
++; dest is the destination to supply for reaching that number. The
++; following variables can be used in the destination string and will
++; be automatically substituted:
++; ${NUMBER}: The number being requested
++; ${IPADDR}: The IP address to connect to
++; ${SECRET}: The current rotating secret key to be used
++;
++; Further options may include:
++;
++; nounsolicited: No unsolicited calls of any type permitted via this
++; route
++; nocomunsolicit: No commercial unsolicited calls permitted via
++; this route
++; residential: This number is known to be a residence
++; commercial: This number is known to be a business
++; mobile: This number is known to be a mobile phone
++; nocomunsolicit: No commercial unsolicited calls permitted via
++; this route
++; nopartial: Do not search for partial matches
++;
++; There *must* exist an entry in mappings for DUNDi to respond
++; to any request, although it may be empty.

++; The remaining sections represent the peers
++; that we fundamentally trust. The section name
++; represents the name and optionally at a specific
++; DUNDi context if you want the trust to be established
++; for only a specific DUNDi context.
++;
++; inkey - What key they will be authenticating to us with
++;
++; outkey - What key we use to authenticate to them
++;
++; host - What their host is
++;
++; order - What search order to use. May be 'primary', 'secondary',
++; 'tertiary' or 'quartiary'. In large systems, it is beneficial
++; to only query one up-stream host in order to maximize caching
++; value. Adding one with primary and one with secondary gives you
++; redundancy without sacraficing performance.
++;
++; include - Includes this peer when searching a particular context
++; for lookup (set "all" to perform all lookups with that
++; host. This is also the context in which peers are permitted
++; to precache.
++;
++; noinclude - Disincludes this peer when searching a particular context
++; for lookup (set "all" to perform no lookups with that
++; host.
++;
++; permit - Permits this peer to search a given DUNDi context on
++; the local system. Set "all" to permit this host to
++; lookup all contexts. This is also a context for which
++; we will create/forward PRECACHE commands.
++;
++; deny - Denies this peer to search a given DUNDi context on
++; the local system. Set "all" to deny this host to
++; lookup all contexts.
++;
++; model - inbound, outbound, or symmetric for whether we receive
++; requests only, transmit requests only, or do both.
++;
++; precache - Utilize/Permit precaching with this peer (to pre
++; cache means to provide an answer when no request
++; was made and is used so that machines with few
++; routes can push those routes up a to a higher level).
++; outgoing means we send precache routes to this peer,
++; incoming means we permit this peer to send us
++; precache routes. symmetric means we do both.
